Buying Guide: How to Choose a Fish Finder Under 100

It would be careless and foolish to settle for the first fish finder you come across. You want to consider a few factors before making your purchase such as:

Depth Range

You want to consider where you will be fishing to determine how deep your fish finder can go to detect fish. For instance, if you will be fishing from a shore or dock, a depth range of 100 meters will do.

Fish finders with more depth are suitable if you will be using a boat to fish.

Display Size

A bigger fish finder screen will give you a clearer view of what is under water. However, affordable fish finders tend to have small screens and if yours is among these, you can link it with your smartphone to get clearer and larger images.

Frequently Asked Questions

Here, we have answered a few questions that will help you get a clearer picture on what we are discussing.

What is the best cheap fish finder?

There are a number of affordable fish finders to choose from so we cannot pinpoint one in particular. Look at the features of a fish finder to determine whether it is worth the investment or not.

Which is better side or down imaging?

Generally, side imaging offers more proportional range than down imaging. When it comes to depth range, down imaging wins.

If you want to be on the safe side, you can go for a fish finder that combines the two.

Best Overall Choice

VenteriorVT-FF001 Fish Finder is our favorite fish finder under 100 with a neck strap to prevent it from falling into the water. In addition, the fish finder is easy to use and has a back light for night viewing.

Final Thoughts
